For the best part of a decade, US officials and cybersecurity companies have been naming and shaming hackers they believe work for the Chinese government. These hackers have stolen terabytes of data from companies like pharmaceutical and video game firms, compromised servers, stripped security protections, and highjacked hacking tools, according to security experts.

Since the start of 2022, China’s Foreign Ministry and the country’s cybersecurity firms have increasingly been calling out alleged US cyberespionage. Until now, these allegations have been a rarity. But the disclosures come with a catch: They appear to rely on years-old technical details, which are already publicly known and don’t contain fresh information. The move may be a strategic change for China as the nation tussles to cement its position as a tech superpower.

“These are useful materials for China’s tit-for-tat propaganda campaigns when they faced US accusation and indictment of China’s cyberespionage activities,” says Che Chang, a cyber threat analyst at the Taiwan-based cybersecurity firm TeamT5.

China’s accusations, which were noted by security journalist Catalin Cimpanu, all follow a very similar pattern. On February 23, Chinese security company Pangu Lab published allegations that the US National Security Agency’s elite Equation Group hackers used a backdoor, dubbed Bvp47, to monitor 45 countries. The Global Times, a tabloid newspaper that’s part of China’s state-controlled media, ran an exclusive report on the research. Weeks later, on March 14, the newspaper had a second exclusive story about another NSA tool, NOPEN, based on details from China’s National Computer Virus Emergency Response Center. A week later, Chinese cybersecurity firm Qihoo 360 alleged that US hackers had been attacking Chinese companies and organizations. And on April 19, the Global Times
